Title: Disc holding device
Inventor: WAKABAYASHI MANABU
IPC: G11B17/03
Filed: 1981-10-26
Abstract: PURPOSE:To improve the accuracy of positioning of the center of a disc, by providing taper inscribed with a center opening of a hub to the center of a center table, and projecting a center boss freely rotatably and movably up and down. CONSTITUTION:A slope of a center boss 13 contacts the lower end of a center opening 3 of a hub 2. Since a chamfering angle of a chamfering section 19 is generally 45 deg., an angle theta taking a plane of the center table 6 of the slope of the center boss 13 as a reference is set at 45 deg.<theta<90 deg., then the center boss 13 moves up and down even if the circular diameter of the opening 3 is dispersed to inscribe the slope of the center boss 13 with the opening 3, allowing to align the disc 1 to the center. The accuracy of disc centering is entirely independent of the processing accuracy of the opening 3, and dependent on the slope of the center boss 13 and the coaxial accuracy of a sleeve 14.

Title: Electric antenna device
Inventor: YANASE SUMIO
IPC: H01Q1/10
Filed: 1989-07-01
Abstract: PURPOSE:To accurately extend and shorten an antenna guide even if bending occurs at the time of winding by using resin wire having a rack part which is driven by means of a pinion gear. CONSTITUTION:The tip part of a cable 1 wound to a bobbin 11 is engaged to the lower end of an antenna element 41 while the rack part 521 is engaged with the pinion gear 2 midway. When the pinion gear 2 turns clockwise, the cable 5 is transmitted upward so as to energize the antenna element 41 upward, and therefore the antenna guide 4 extends. When the pinion gear 2 turns counterclockwise in a state that the antenna guide 4 is extended, the cable 5 is wound to the bobbin 11 and energizes the antenna element 41 downward, and therefore the antenna guide 4 is extended and shortened. Since the rack part 521 is in resin wire 52 at that time, it is securely driven by the pinion gear 2.

Abstract: PROBLEM TO BE SOLVED: To sufficiently reduce release time lag and to improve operability by expanding a sweeping area in the case of high brightness where appropriate storage time is short and reducing an effective output area in accordance with the brightness of a subject. SOLUTION: A read controlling means (timing generates 6 and CPU 8) controls a reading mode in which it vertically transfers signal change stored in a valid area of an image pickup device within an effectively horizontal scanning period in such timing as to transfer it in a relatively rough frequency and reads it and a sweeping mode in which it vertically transfers signal charge stored in an unneeded area of the image pickup device within the effectively horizontal scanning period in such timing as to transfer it in a relatively close frequency and reads it. An area setting means (CPU 8) sets the ranges of a valid area and an unnecessary area. And this device expands a sweeping area in the case of high intensity where appropriate storage time is short in accordance with the brightness of a subject and reduces an effective output area.

Abstract: PURPOSE:To quickly execute detection of the presence of a cassette by detecting a light output from a light emitting means with both light receiving means positioned on both sides of a tape-shaped recording medium and detecting the absence of the cassette based on the detected result. CONSTITUTION:An information as to whether the light output L from a light emitting element 21 is detected or not by a light receiving element 22T is usually the information as to whether it is the top of a tape or not. That is, after that an output corresponding to the quantity of light receiving by the element 22T is converted to digital level data by an A/D converter part 37 and a level calculation part 38, whether it is the top of the tape or nor, is detected by a controller part 31 based on the output of a comparator 40. At this time, in the case of detecting the top of the tape or in the case of detecting the end of the tape is in the case that the light L is detected by the light receiving elements 22S and 22T. Therefore, the processing for case where not cassette in loaded, is executed if it is judged that no cassette exists.

Filed: 1991-06-17
Abstract: PURPOSE:To improve image quality by providing an abutting part for a processing cartridge other than a center positioning part of a photosensitive drum on main body frame side. CONSTITUTION:An opening/closing cover 5 is closed until a lock hole part 5c is engaged with a lock.

Filed: 1994-06-30
Abstract: PURPOSE:To enable the cordless telephone set to discriminate whether a slave set is resident in the coverage zone or in the outside of it and to inform the slave set of the fact even when the slave set is in a standby state. CONSTITUTION:Every time a slave set timer 28 counts a prescribed time and outputs a time-out signal in a slave set 2, a slave set radio section 21 sends a registration signal to a master set 1. Upon the receipt of the registration signal by a master set radio section 12, the master set 1 sends a response signal to the slave set 2. When the slave set 2 cannot detect the response signal within the count time of the slave set timer 28, the slave set 2 drives an out of zone alarm generating section 27 under the control of a slave set control section 24 to perform the report of the residence at the outside of the coverage zone while the slave set 2 receives the response signal.
